Theory. Cutting speed is the relative linear velocity between the tip of the cutting edge and the workpiece. It is a result of the product between the rotation speed of the milling cutter ( Spindle speed) and its circumference. C = 2 × π × r = π × d. V c = n × C. Important Note: The Diameter (d) should be the effective diameter and not ...Web

Up until the late 19th century, most millers used mill stones to mill the wheat into flour. Mill stones always come in a pair. Both are large round stones, with a flat top and bottom and are incredibly heavy. The bottom stone, the bed stone, stands still during the milling process. The top stone, or roller stone, rotates on top of the bed stone.Web
